Hand-held laser level grade checking device

摘要: A tool for use in checking the level or grade of ground surface a construction area site using daylight visible wavelength semiconductor laser diode module to project beam from location interest where elevation amount cut fill is known. The relatively small, hand-held and compact device that utilizes batteries contained within power diode. fits plug compartment front tool. end cap encloses emitted axial alignment with an edge ridge on outside bubble ensures held parallel during use.
